Charlie Marsh d9f9ed4aec Reuse build (virtual) environments across resolution and installation (#14338) ... ## Summary The basic idea here is that we can (should) reuse a build environment across resolution (`prepare_metadata_for_build_wheel`) and installation. This also happens to solve the build-PyTorch-from-source problem, since we use a consistent build environment between the invocations. Since `SourceDistributionBuilder` is stateless, we instead store the builds on `BuildContext`, and we key them by various properties: the underlying interpreter, the configuration settings, etc. This just ensures that if we build the same package twice within a process, we don't accidentally reuse an incompatible build (virtual) environment. (Note that still drop build environments at the end of the command, and don't attempt to reuse them across processes.) Closes #14269.		2025-07-01 13:15:47 -04:00
